One smaller thing is that XML::Genx is XS-based, which means we'll need a C compiler for all the platforms we intend to deploy on. Luckily, there are only two platforms, Linux/SuSE for pmdev and *BSD for the production machines. There will be problems if Pair upgrades the Perl version of the servers, as then XML::Genx will have to be (re)compiled in lockstep with the upgrade. But maybe we can somehow arrive in an arrangement with Pair regarding that.

Adding XS code also means that we could run afoul of (more?) spurious segfaults, but if we restrict ourselves to one new XS module/one XS upgrade every month, the source of the segfaults should be fairly traceable.
